Title:
On the Buckling/Kinking Compressive Failure of Fibrous Composites

Abstract:
In this article it is demonstrated that the compressive response of unidirectionally reinforced composites may initiate in a micro-buckling mode and subsequently switch to a micro-kinked configuration. The foregoing possibility derives from a mechanics model which considers initial fibers misalignments, non-linear shear response of the matrix, shear deformable fibers and stochastic fiber spacings. The latter non-uniformity in fiber spacings plays a major role in the generation of fiber kinks. Various features of the compressive deformation and failure process are exhibited by computational examples.
